Each option can add a flat amount to the price, and shoppers see a live running total as they make their selections — before they even click Add to Cart. Every price is a flat amount you enter yourself and it’s looked up fresh from the product whenever something is added to the cart — there is no formula language, expression evaluator, or anything resembling `eval()` anywhere in this plugin. That’s a deliberate design choice: a well-known paid “product add-ons” plugin for WooCommerce disclosed a critical, unauthenticated Remote Code Execution vulnerability caused by unsafely evaluating merchant-defined pricing formulas. This plugin gets the same practical result (customers pay more for the options they pick) without that entire class of risk. #### Key Features * Text, dropdown, and checkbox product options, each with an optional flat price adjustment * A live price preview updates on the product page as customers fill in options, before adding to cart * Works correctly everywhere in WooCommerce: the product page, cart, Mini-Cart, Checkout (classic and block-based), the order confirmation page, order emails, and the admin Edit Order screen — all using WooCommerce’s own standard cart/order mechanisms, not a separate parallel system * Required options are enforced on the server, not just with a browser-side `required` attribute — a request that skips a required option is rejected before it reaches the cart * Every submitted option value is re-validated against the product’s own current configuration before any price is applied, so a tampered request can’t fabricate a discount or a fake option * No formula evaluation of any kind — every price is a flat, merchant-entered amount #### Limitations (please read before installing) * Simple products only — variable, grouped, and external products aren’t supported in this version * Flat-amount pricing only — there’s no percentage-of-price option and no pricing formulas; this is a deliberate security boundary as well as a simplicity one ( see Description) * No conditional logic between options (e.g. showing one option only when another has a specific value) * Options are configured per product — there’s no shared, reusable option set applied across multiple products in this version ### How to Use #### 1. Open a simple product for editing Go to **Products** and open any _simple_ product (the tab only appears for simple products in this version). #### 2. Add your options Click the new **Options & Add-ons** tab under Product Data (Screenshot 1). Click** + Add Option** for each option you want: give it a label, choose Text field, Dropdown, or Checkbox, optionally mark it required, and set a price adjustment. For a Dropdown, click **+ Add Choice** to add each choice with its own price. Click **Update** to save. #### 3. What shoppers see On the product page, your options appear above the Add to Cart button (Screenshot 2), each showing its price adjustment. As shoppers fill them in, a live “Total with options” preview updates automatically. #### 4. Cart, Checkout, and orders The chosen options and their price adjustments show on the cart, Mini-Cart, and Checkout (Screenshot 3), on the order confirmation page and order emails, and on the admin Edit Order screen (Screenshot 4) — all automatically, using WooCommerce’s own standard display mechanisms. ## Screenshots [⌊The "Options & Add-ons" tab in Product Data, adding text, dropdown, and checkbox options.⌉⌊The "Options & Add-ons" tab in Product Data, adding text, dropdown, and checkbox options.⌉[ The “Options & Add-ons” tab in Product Data, adding text, dropdown, and checkbox options.
